Genus
The great raven-like bird — the ground hornbills
Literally: ox-raven (or: great raven)
| Part | Meaning | Language | Note |
|---|---|---|---|
| Bu- | an ox, a cow; used as an intensifying prefix meaning 'large' or 'great' | Greek (bu / bou) | Greek βοῦς (bous); the combining form bu- is used before a consonant. Both bu and bou are confirmed in the dictionary. |
| -corvus | a crow, raven | Latin (corv, =us) | Latin masculine noun; functions as the head noun, giving the whole genus its grammatical gender (masculine). Confirmed in dictionary as corv, =us. |
Bucorvus is a single compound genus name formed by prefixing the Greek intensifying/size prefix bu- (ox, great) directly to the Latin noun corvus (raven, crow), without a connecting vowel (none is needed since bu- already ends in a vowel and corvus begins with a consonant). The compound is treated as a Latin masculine noun under ICZN rules. It is a deliberate Greek–Latin hybrid, a common 19th-century taxonomic practice. The genus (erected by Lesson, 1830, when splitting ground hornbills from Buceros) contains the two extant species of ground hornbills — the largest of all hornbills, hence 'the great ravens'.
Pronunciation
- byoo-KOR-vus Penult rule 5: the word has three syllables (Bu-cor-vus); the penult vowel o is short, but it is followed by two consonants (r then v), so the penult is heavy and receives the stress.
Other readings
Some analysts read Bu- not as the raw Greek root bou/bu (ox) but as a clipped form of the genus name Buceros (from Greek bou- + keras, horn = 'ox-horned', the typical hornbills), giving Bucorvus the sense 'hornbill-raven'. This reading is historically attractive because Lesson erected Bucorvus by splitting it out of Buceros, but the simpler ox/great + raven reading is equally valid and more directly etymological.
Both segments are confirmed in the dictionary: bu / bou (Greek, 'an ox / a cow') and corv =us (Latin, 'a crow, raven'). Bucorvus is a Greek–Latin hybrid compound. Such hybrids are nomenclaturally valid under ICZN rules even though classical purists discourage mixing source languages. The intensifying use of bou-/bu- ('great, large') is well attested in Greek scientific compounds (e.g. Bubalus, buffalo; Buceros, large-horned), making 'great raven' the most natural English rendering for a genus of unusually large, crow-like birds.
